No entanto, se você usar `pip` diretamente, os pacotes serão instalados no seu **ambiente Python global** (a instalação global do Python).

### O Problema { #the-problem }

Então, qual é o problema em instalar pacotes no ambiente global do Python?

Sin embargo, si solo usas `pip` directamente, los paquetes se instalarían en tu **entorno global de Python** (la instalación global de Python).

### El Problema { #the-problem }

Entonces, ¿cuál es el problema de instalar paquetes en el entorno global de Python?

Natürlich gibt es Fälle, in denen es kein Problem darstellt, die Vorab-Schritte mehrmals auszuführen. In diesem Fall ist die Handhabung viel einfacher.

 *  Fix: Don't drop uncaught exceptions thrown in async calls.
 *  Fix: Throw an exception eagerly when a request body is not legal. Previously
    we ignored the problem at request-building time, only to crash later with a
    `NullPointerException`.
 *  Fix: Include a backwards-compatible `OkHttp-Response-Source` header with
    `OkUrlFactory `responses.

    //     imagine a line separating the first block from the second, we can proceed by exchanging
    //     the smaller of these blocks with the far end of the other one. That leaves us with a

    //     Say we are rotating abcdefgh by 5. We start with abcde|fgh. The smaller block is [fgh]:
    //     [abc]de|[fgh] -> [fgh]de|[abc]. Now [fgh] is in the right place, but we need to swap [de]
